。Conventionally, it has been pointed out that extruded tubes made of plastic still have problems in terms of extrusion characteristics and the occurrence of airbags. First, after pressing the food tube to extrude the contents, when this pressing force is released, the tube tends to return to its original shape due to the elastic recovery force of the tube itself. There is a tendency to suck not only the contents but also the outside air into the cylindrical body. This suction of outside air occurs before resealing with the cap, so the contents inside the tube come in contact with the cloudy outside air, causing problems such as oxygen and airborne microorganisms (such as deterioration, discoloration, loss of flavor, and loss of aroma). In addition, when reusing the package, if the air inside the tube is not exhausted, the contents may not be pushed out as desired, or the contents may be violently expelled at the same time as the internal air is expelled. It is easy to cause problems such as scattering.
従って、本発明の目的は、上述した欠点を解消した内容

意のものであってよいことは当然である。In this specific example, the tube container 1 is formed by blow molding (inner wall molding) the thermoplastic resin parison, and each part is integrally formed, and the orifice passage 8 is formed by meshing the diameter of the tube with the mold. It is designed to narrow this down. In this specific example, as shown in FIG.
Although the cross-sections are circular, it goes without saying that these cross-sectional shapes may be arbitrary.

。Now, if we press the cylindrical body 4 of the tube container package filled with contents to extrude 9 parts 6 of the viscous contents, and then observe the state in which the pressing force of the cylindrical body 4 is released, we can see that 5-
This is a continuation of Figure A and Figure 5-B. That is, as shown in Fig. 5-A, when the cylindrical body 4 is pressed and the contents are taken out, it is at a position Fo that overlaps with the front end opening 60 of the contents, but when this pressing force is released, Due to the elastic restoring force of the cylindrical body part 4, the viscous contents 6 in the retention part 10 are sucked into the cylindrical body part, and the distal end surface has a concave center as shown in Figure 5-A. As the viscous contents 6 are further sucked into the parabolic rotation surface F1, as shown in Figure 5-B, the contents in the center are strongly sucked, and finally air is drawn into the center. A passage 11 is now formed. In the state where this air passage 11 is formed, air is sucked into the tube container in broad daylight, and the contents and air come into contact over a wide contact area.
It has already been detailed that various types of deterioration occur.

に位置するようにすることが重要となる。In the fogger of the present invention, after the contents are extruded from the tube container and used, the tip of the viscous material in the retention part 10 is kept for 9 hours, generally about 20 seconds, until the cap 2 is covered and resealed. It is important that the surface is also located on the push tooth opening side beyond the limit position F2 shown in FIG. 5-C.

る。According to the results in Figures 6-A and 6-B, the above formula (1a)
It is clear that this has an extremely critical meaning in preventing airbags, and by determining the dimensions of the container and the viscosity of the contents so as to satisfy the above formula (1), airbag prevention becomes possible. In other words, when the content of a certain viscosity becomes difficult, airbag prevention can be achieved by increasing the axial distance of the retention section 10 and increasing the ratio of the retention section cross-sectional area (Sl)/orifice cross-sectional area (So>). It can be seen that for tube containers with constant dimensions, increasing the viscosity of the contents is effective in preventing airbags.

The case where the resilience E of is 502 is shown. In the plot of the experimental results, the circle mark (○) indicates that the state of the viscous substance in the container 20 seconds after the contents were taken out was the state shown in Figure 5-A, and the rose mark (X) indicates the state after the content was taken out. The state of the viscous material after 20 seconds is 5th.

The above formula (2) also has critical significance in preventing airbags, and it is clear that the airbag phenomenon is effectively prevented in the region above the following formula (%). That is, it can be seen that for contents having a constant viscosity, reducing the cross-sectional area, S, of the orifice passage 8 or reducing the compression recovery force of the body 4 is effective in preventing airbags.

減少を生じてエアバック防止効果は望み得なくなる。In the present invention, when the pressing force of the tube container body 4 is released and the viscous material in the retention part 10 is sucked into the container, the tip surface becomes parabolic as shown in FIG. 5-A. In order to reduce the volume so as to achieve the state shown by the curved rotating surface or conical surface F, the retention portion 10 is made to have a relatively large cross-sectional area S1, and the oriSwiss passage 8 is made to have a relatively small cross-sectional area S. It is also important to close the tube and form a step between the two, so if the mouth of the tube container has a straight cross section, the volume will be reduced so that the entire tip of the contents descends. This will result in no airbag prevention effect.

In particular, by setting the number to 6 or more, a satisfactory airbag prevention effect can be achieved. On the other hand, if this cross-sectional area ratio Sl/So becomes too large, the extrusion characteristics (squeezing characteristics) will deteriorate and the shape of the container will also deteriorate, so the value of S, /So should be 20.
Hereinafter, it is desirable that the percentage is 10 or less.
